public class PreciseDateTimeField extends PreciseDurationDateTimeField
Precise datetime field, composed of two precise duration fields.This DateTimeField is useful for defining DateTimeFields that are composed of precise durations, like time of day fields. If either duration field is imprecise, then an
ImpreciseDateTimeField
may be used instead.PreciseDateTimeField is thread-safe and immutable.
